PREOPERATIVE EVALUATION OF CYSTIC TERATOMA - WHAT DOES COLOR DOPPLER ADD

The aim of this prospective study lasting 4 years was to develop a sco ring system using clinical parameters, sonographic findings, and trans vaginal color and pulsed Doppler impedance values for the preoperative recognition of cystic teratoma. A total of 887 benign and malignant a dnexal masses, among which 102 were histologically proved to be cystic teratomas, were evaluated. Using morphological criteria, cystic terat oma was successfully predicted in 95 patients. The sensitivity and spe cificity of a morphological scoring system were 93.1% and 99.4%, respe ctively, while positive and negative predictive values were 95.0% and 99.1%. A scoring system using both morphology and vascular assessment demonstrated higher sensitivity and specificity (99.02%, 99.75%). The application of a scoring system combining morphology and vascularity i mproves the accuracy of diagnosing cystic teratoma and of separating t his entity preoperatively from other benign and malignant ovarian cond itions.
